What the parent post is demonstrating is how much the OP's question is a non sequitur. Quality is always going to be measured by domain so asking for a list of measurable qualities outside of context is unanswerable. Skills that amount to the "hello world" of web development can be worth hundreds of thousands of dollars to an expanding or new company, but are worth less than pennies to a Netflix. Trying to measure quality without context is, imo, one of the biggest drivers to the cluster fuck that is tech recruiting.
